Cisco G.SHDSL High Speed WAN interface Card with IEEE 802.3ah EFM Support for Cisco Integrated Services Routers
Cisco® Integrated Services Routers (ISRs) and Integrated Services Routers Generation 2 (ISR G2) offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The Cisco single port 4-pair G.SHDSL High Speed WAN Interface Card (HWIC-4SHDSL-E) offers G.SHDSL-based WAN connectivity using the 802.3ah Ethernet in the First Mile (EFM)-compliant extended rate symmetric high-bit-rate DSL (SHDSL) EFM (2BASE-TL) technology for modular routers deployed in small to medium-sized businesses and enterprise branch offices.
The Cisco 4-pair G.SHDSL High Speed WAN Interface Card is designed to deliver high-speed Ethernet services over SHDSL access. HIWC-4SHDSL-E allows bonding to achieve higher data rates as defined by IEEE 802.3ah, and it is typically used in scenarios where individual links are aggregated using the 802.3ah loop aggregation. This card is supported in all Cisco ISR (except the Cisco 3825 and 2811) and ISR G2 routers that have HWIC slots.
The HWIC-4SHDSL-E comply with 2BASE-TL, which is based on the IEEE 802.3ah EFM standard. The 2BASE-TL standard uses the technology standard based on ITU recommendation G.991.2 bis.
The HWIC-4SHDSL-E cost-effectively allows service providers and enterprise customers to deliver Ethernet services to sites with no access to fiber by using bonded copper pairs with symmetrical bandwidth at rates up to 4 x 5.696 Mbps.
The HWIC-4SHDSL-E together with Cisco ISRs provides businesses the necessary bandwidth for critical traffic such as voice and video conferencing, and enables customers to save money by integrating voice and data traffic on the same WAN link. Service providers can increase subscriber revenue by bundling services and offering differentiated service levels through service-level agreements (SLAs).
This Interface Card enables point-to-point Ethernet connectivity, which uses existing infrastructure of copper wires spanning a typical carrier service area (CSA) of 9,000 to 12,000 feet from a central office to the customer premises.
The symmetric DSL, G.SHDSL has been an accepted worldwide technology standard based on ITU recommendation G.991.2. The 4-pair G.SHDSL EFM HWIC is designed to transport rate-adaptive symmetrical data across a single copper pair and EFM bonding with Annexes F and G up to 4 x 5.696 Mbps. These rates cover applications traditionally served by HDSL, single-line DSL (SDSL), T1, E1, and services beyond E1. Refer to Table 2 for the data rates supported by the 4-pair interface card (HWIC-4SHDSL-E) under different configurations.
